HERBERT J. PAGE, OF ST. MARYS, CANADA.

AUTOMATIC GOVERNOR-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 549,528, dated November12, 1895.

Application filed May 4, 1895. Serial No. 548,177. (No model.)

To all whom it may concern:

Be it known that I, HERBERT J. PAGE, a subject of the Queen of GreatBritain, and a resident of St. Marys, in the Province of Ontario,Canada, have invented a new and useful Automatic Governor-Regulator, ofwhich the following specification, taken in connection with theaccompanying drawings, forms a full, clear, and exact description.

This invention relates to a certain new and useful speed-regulator forthe governors of steam-engines, water-wheels, and the like, and has forits object to provide a device whereby said governors may beautomatically regulated to run at a uniform rate of speed under varyingloads and steam-pressures; and this invention consists of a weight inthe form of a segmental plate or bar arranged above its pivotal support,which plate or bar is instantly and automatically adjusted by thegovernor to move more or less to either side of its pivotal support toincrease or decrease its resistance to the governor, and also of thecombinati0n,with the above,of a flexible connection for said plate orbar with the governor-spindle and to adapt it to set or regulate thespeed or for the purpose of adapting a single device to regulategovernors of difierent speeds.

In order that my improvements may be better understood,I haveillustrated in the accompanying drawings an automatic speed-regulatorconstructed according to my invention, in which- Figure 1 is a sideelevation of a governor and an automatic speed-regulator embodying myinvention. Fig. 2 shows the application of same to another form ofengine and governor.

In the drawings, S designates a suitable sup port for the governor, Hthe governor-spindle, and I I the governor-balls.

A designates a lever pivotally supported on the stud a, the latter beingsecured to the support S. The arm I) of said lever A is pivotallyconnected with the governor-spindle H. C designates a chain or otherflexible or yielding connection, which extends from and connects the armd of said lever A with the segmental bar or plate D,and crepresentssuitable means for adjusting or varying the length of the con- 'nection.

D designates a weight bar or plate, which may be in the form of anysegmental part of a circle or other geometric figure and pivotallysupported on the pivot e, the latter being held in place and supportedby an arm or support E.

In Fig.1 the governor-spindle H is connected with the valve-gear, (notshown,) and in Fig. 2 the lever A is connected by the connectingrod 19with the valve-gear. (Not shown).

The operation is as follows: When the load is increased or thesteam-pressure reduced, the governor-balls will take the lower position,(designated by dotted line F,) and with the attachment of this segmentalbar or plate D in the form shown the resistance to the centrifugal forceof the governor-balls is increased or becomes greater, because thesegment D is adjusted to the position shown by dotted line G, or agreater portion thereof will be adjusted to the side of its pivotalsupport opposite to or against the governor. Consequently this greaterportion will act as an increased resistance to the centrifugal force ofsaid governor-balls; and if the load should be reduced or thesteam-pressure increased the governor-balls would take the higherposition, (designated by dotted line K,) and with the attachment of thisweight D the resistance to the centrifugal force of the governor-ballsis reduced or becomes less, because the segmental bar D is adjusted tothe position shown by dotted line L, or a greater portion thereof willbe adjusted to the same side of its pivotal support as the governor.Consequently this will reduce the resistance of the segmental bar orplate D to the centrifugal force of said governor-balls, because theportion of the weight on the same side of its pivotal support as thegovernor will counteract an equal weight on the side of the segmentalplate opposite to the governor. As a result, this weight, operating asdescribed,oifers less resistance to the governor as the latter tries tolift it, so that as the governor experiences greater difficulty inraising the balls to a higher plane the weight to be lifted becomeslighter, and this segmental bar or plate offers greater resistance tothe governor on its reverse action, thus securing a more constant actionof the governor, and consequently a more regular speed of the engine.

In order to regulate different speeds with the one device, additionalweights, segmental plates, or bars may be secured to the one in use orpivotally supported on the pivot e, or said segmental plate or bar D maybe adjusted more or less to either side of its pivotal sup port. \Vhensetting the speed by adjusting the segmental bar or plate D toward thedotted line G, this plate or bar acts as a resistance or is set againstor regulates a governor of a higher speed. The reverse result would beaccomplished by setting said segmental bar or plate in the direction ofthe dotted line L.

The constructions herein shown and described I have found by experimentto give the best results; but the segmental bar or plate may be formedof a straight or curved bar, plate, or tube and with or without anenlarged weighted rim, (without an enlarged weighted rim by constructingthis device of a segmental plate and distributing the weight equallyover said plate;) or this segmental bar may be in the form of a circleor wheel the rim of which is weighted unequally; or this segmental plateor bar maybe connect-ed with the trip-shaft of another form of engine orbe connected with a counter-shaft and an arm from this shaft or from thesegmental bar or plate engaging with the governor-spindle, so that,while I prefer the construction shown, I do not limit myself to thedetails thereof,

as they may be modified in various ways with-v out departing from thespirit of my invention. Having thus described my invention, I claim In agovernor regulator the combination of a suitable support, a leverpivoted on said support, and connected at one end with the governorspindle, a segmental weight pivoted on said support,a flexibleconnectionbetween the segmental weight and the free end of the pivotedlever, and suitable means for adjusting the connection substantially asshown and for the purpose set forth.

In testimony whereof I have signed in the presence of the twoundersigned witnesses.
